TL;DR

This paper develops a steady state theoretical framework within a tight binding model to quantify current transfer efficiency, explaining asymmetries in electron transfer induced by circularly polarized light in helical wires.

Contribution

It introduces a steady state theory of current transfer in coupled wire systems, linking asymmetry to system response under imposed steady currents.

Findings

Current transfer causes measurable asymmetry in electron transfer.

Theoretical model quantifies transfer efficiency based on asymmetry.

Steady state approach explains observed asymmetries in experiments.

Abstract

Current transfer is defined as a charge transfer process where the transferred charge carries information about its original motion. We have recently suggested that such transfer causes the asymmetry observed in electron transfer induced by circularly polarized light through helical wires. This paper presents the steady state theory of current transfer within a tight binding model of coupled wires systems. The efficiency of current transfer is quantified in terms of the calculated asymmetry in the system response to a steady current imposed on one of the wires, with respect to the imposed current direction.
